Benefits of technology

The patent aims to provide an electrical connector with a strong grounding effect to enhance the quality of signal transmission.

Problems solved by technology

Since the tongue portion is usually thinner than the base, the strength of the tongue portion maybe not strong enough.
Since the first contacts and the second contacts are adjacent with each other, signal interference generated therebetween may render poor signal transmission quality.

Abstract

An electrical connector includes an insulative housing, a number of contacts retained in the insulative housing, a metallic outer shell enclosing the insulative housing, and a metallic inner shell positioned between the metallic outer shell and the insulative housing. The insulative housing includes a base and a tongue portion protruding from the base. The contacts include a number of flat contacting portions exposed on a top surface and a bottom surface of the tongue portion, respectively. The tongue portion is located at a center of the metallic outer shell along a vertical direction. The metallic inner shell and the metallic outer shell are in mechanical contact with each other in order to achieve a relative larger grounding area.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the priority of Chinese patent application Ser. No. 201410445110.9 filed Sep. 3, 2014 in the SIPO (Sate Intellectual Property Office of the P.R.C.), which is incorporated by reference herein in its entirety.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates to an electrical connector, and more particularly to an electrical connector having a metallic inner shell and a metallic outer shell in contact with each other for realizing robust grounding effect.[0004]2. Description of Related Art[0005]A conventional I / O connector for being mounted to a circuit board usually includes an insulative housing, a plurality of contacts retained in the insulative housing and an outer shell enclosing the insulative housing. The insulative housing usually includes a base and a tongue portion extending from the base. Since the tongue portion is usually thinner than the base, the strength of the tongue portio...
